don draper's bitter end

1 oz Rye (Rittenhouse)
1 oz Cognac (Courvoisier VS)
1/2 oz Averna
1/4 oz Fernet Branca
1/4 oz Orange Liqueur (Pierre Ferrand Dry Curaçao) (*)
2 dash Angostura Bitters

Stir with ice, strain into an old fasioned glass with ice, and garnish with an orange twist.
(*) An adaptation added to the original recipe. Two Mondays ago, I was perusing the Kindred Cocktails database when I came across Don Draper's Bitter End created at Hank's Oyster Bar in Alexandria, Virginia, circa 2014. The recipe posted there was an adaptation of the original that included the addition of orange liqueur for sweetness. I found the rye, Fernet, and orange liqueur combination reminscent of the Alcazer from Pioneers of Mixing at Elite Bars: 1903-1933, so I went with it. Once stirred and strained, the Don Draper's Bitter End gave forth orange, Cognac, caramel, and menthol aromas. Next, a caramel-driven sip soon advertised rye, Cognac, orange, bitter gentian, and minty-menthol flavors on the swallow.
